Specification of Letters Patent.

Patented June 28, 1921.

Application filed October 23, 1919. Serial No. 332,821.

T 0 all whom it may concern:

Be it known that I, ALFRED DUNHILL, a subject of the King of Great Britain nd Ireland, residing at London, England, have invented certain new and useful Improvements in Apparatus for Seasoning and Finishing Tobacco-Pipes, of which the following is a specification.

This invention relates to apparatus for seasoning and finishing tobacco pipes made from briar and other wood.

In the manufacture of these articles it is often desirable to employ oils, but the employment of such oils is open to the objection that when the pipe is first used, the heat of the burning tobacco causes the oil to exude, imparting an unpleasant flavor to the smoke and destroying the appearance of the outer surface of the pipe.

My present invention relates to improved means for overcoming this drawback, and relates to a seasoning and heating apparatus which enables the pipes to be treated with oil and quickly prepared for use, without it being necessary to store them away for long periods, as has been usually the practice after treating pipes with oil, in order to prevent superfluous oil being exuded during the process of smoking.

In order that my said invention may be clearly, understood, I will now proceed to describe the same with reference to the accompanying drawing, in which Figure 1 is a vertical section of one form of the apparatus for seasoning the pipes.

Fig. 2 is'a plan of the same.

Fig. 3 is a longitudinal view of another form of the apparatus and,

'Fig. at is a perspective view of one end of the same apparatus, with the door broken away for the sake of clearness.

Referring to Figs. 1 and 2, a is a hot plate, supported upon the table or the like I) by legs or other suitable standards 0.

A space between the lowervsurface of the hot plate a and the table forms a cylindrical or other suitably shaped chamber (Z. The depending sides 6 of the chamber are formed of asbestos or otherheat insulating material, and may, if found necessary be incased in an outer shell f of sheet metal.

Within the chamber 03 is placed a gas ring 9 connected to a supply pipe 71..

The hot plate a is provided with any suitable number of holes or perforations, preferably arranged in two concentric rings at or near the periphery of the plate a. Within these holes are placed plugs in on which the bowls of the pipes p are supported.

The plate a is also provided with a central hole or aperture Z to which is connected a pipe 777. for conveying away the products gf combustion from the interior of the cham- The lower portion of the chamber at, which is preferably formed of sheet metal 7?. is provided with a central hole 0, connected to a pipe g, through which atmospheric air is admitted for supporting combustion within the chamber.

When the apparatus is erected in an upper work room, the pipe 9 may be connected to an opening in the ceiling of the work room beneath, as shown diagrammatically at r, so that the apparatus also serves for ventilating the room. or workshopof the floor he- In order to obtain a uniform distribution of the heated gases over the under surface of the hot plate a, a baffle plate 5* is provided. This plate is preferably of the same shapeas the chamber (Zandof such size as to leave an annular space between its periphery and the walls 6 of the chamber.

The baflle plate is conveniently supported inposition at a suitable distance from the;

hot platen by the legs or standards 0.

The chamber d is surrounded by a band or upwardly projecting shield t formed of asbestos, sheet metal or other suitable mate rial.' This shield is located at a short distance from the outer edge of the hot plate a and extends a little higher than the tops of the plugs is, so as to protect the pipes placed thereon from cold drafts of air.

This screen is continued downward as shown and is connected to the walls 6 by the member t 7 i i In utilizing the apparatus, each pipe to be treated is placed upon a plug is. The heat is communicated to the bowls of the pipes, the wood having previously been soaked in oil in the ordinary manner. At suitable intervalsof time, the exuding oil is wiped off from the surface of the wood, so that accumulation and caking of the oil is avoided and after this process has been continued for a sufficient time the pipe is removed.

I find in'practice that the apparatus just described gives admirable results in working, as all. the bowls of the pipes are treated uniformly, a result which is due not only to the perfect distribution of the heated gases over the lower surface of the hot plate, but also to the fact that no cold drafts of air for supplying the gas stove, are set up in the neighborhood'ofthe apparatus."

Referring to the form of the apparatus shown in Figs '3 and 4,1 is a metal frame work provided with longitudinal side walls 2 preferably of iron plate, covered by sheets 3 of asbestos or other heat insulating material. The top of the chamber is closed by a metal plate A constituting the hot plate having a plurality of plugs 5, on which the plpes ported in guides 8,

areplaced. The bottom of the chamber consists of a perforated metal plate 6 One or each of the ends of the chamber preferably consists .of slidabledoors 7 suitably supthe upper edge of the door being conveniently curved or arched at 9 to facilitate handling. 7 The heat generator consists of two burners l0 resting onithe perforated bottom 6 and inserted in the chamber from both ends, the I end doors 7 being suitably slotted or formed with suitably shaped apertures, so asto fit snuglyover'the burners,

he interior of the chamber is provided with a baffleplate or deflector 11: supported by brackets burnerslO and controlled by cocks or taps l5, and'16 isa chimney, preferably. located the center .8 of

The nozzles in the adjacent rows may be staggered as shown in order that the stems of, the pipes'on the inner rows can be conveniently passed between the nozzles in the outer rows or where the nozzles are not staggered the pipesmay be placed in an inclined position in the inner rows for the same purpose. In fact any convenient arrangement of nozzles may be adopted. s
